Corals Closing

[jerryatrick]

My corals begin to close up around 6 pm every night. My Actinics come on around 9AM and are off around 9PM. My 10,000K bulbs come on around 11AM
and go off around 7PM. The corals that I am speaking of are located at the middle part of tank. Xenia, rics, duncan, and candy canes are all located in the middle of the tank. Are these corals telling me that they have had enough light?
I am currently running a Coralife Dual 130 watt PC fixture on a 44 gallon Hex that is 24 inch deep.

FYI... I will not accept "Your lights are to strong" as I know that they aren't. Appreciate it!!!

I very well could be reading my test results wrong. My calcium is high because I raised my SG from 1.021 to 1.025 in a few weeks by adding nothing but mixed salt water. My calcium was in the lower 400s before I raised my SG.
